A method, article of manufacture, and apparatus for efficiently backing up information are disclosed. In some embodiments, this comprises receiving data and analyzing the data. In some embodiments, the data may be manipulated. In some embodiments, the data may come from multiple sources. Chunk headers, data chunks and chunk maps are then created based on analyzing the data. Chunk headers store the data manipulation technique of the data chunk. In some embodiments, chunk headers store the size of the manipulated and un-manipulated data chunks. The chunk headers, data chunks and chunk maps are then organized into a datastream. The datastream is then stored in a storage device. In some embodiments, the received data may be discarded. In some embodiments, a chunk header is associated with a data chunk. |
